As I will be with the Year 9/10 camp, at Rubicon during the first week back at school, you will need to work through Chapters 1 and 2 in class. The Area of study is pollutants, with case studies of mercury, sulphur and fluoride. In the previous post there are some worksheets for you to download and complete.
You may have heard about fluoride in the news recently – there have been bomb threats to Barwon South West Water and a Victorian MP is under police guard after fluoride has been intoruduced to Geelong’s water supply. Warrnambool received fluoride in the water supply last year after many months of contentious debate. Some people claim it is poison, while many scientists and dentists believe it reduces the incidence of tooth decay. Should we consider it as a pollutant?
